The use of rubber seals can well prevent the leakage of lubricating oil or the intrusion of other objects, and has a good protective effect on the equipment. Currently, it has a wide range of uses in the electronic medical and food industries, but rubber seals are used in different applications. The material of the ring may be different. Let's learn about the materials of the rubber seal.

1. Fluorine rubber: It has high temperature resistance, can be used in the environment of -30℃-+250℃, resistant to strong oxidants, oils, acids and alkalis. Usually used in high temperature, high vacuum and high pressure environment, suitable for oil environment. Due to its various excellent properties, fluorine rubber is widely used in petroleum, chemical, aviation, aerospace and other sectors.

2. Silicone rubber: It has outstanding high and low temperature resistance, maintains good elasticity of rubber seals in the temperature range of -70℃-+260℃, and has the advantages of resistance to ozone and weathering. It is suitable for thermal machinery. The sealing gasket.

3. Nitrile rubber: It has excellent resistance to oil and aromatic solvents, but it is not resistant to media such as ketones, esters and chlorinated warp. Therefore, oil-resistant sealing products mainly use nitrile rubber.

4. Chloroprene rubber: It has good oil resistance, solvent resistance, chemical media and other properties, but it is not resistant to aromatic oils. The characteristics of rubber seals are weather aging and ozone aging resistance. In production, neoprene is usually used to make door and window sealing strips and diaphragms and general vacuum sealing products;

5. EPDM: It has good temperature resistance, weather aging resistance and ozone aging performance, usually widely used in door and window sealing strips and automobile industry.
